18 to cont-act with the lower surface of the sill to prevent theelements from passing between the sills, and a similar weather strip issecured to the lower surface of the lintel 19 to bear on the lintal 16to prevent the elements from passing between the lintels. As seen inFig. 1, the upper surfaces of the sills 15 and 13 slope outwardly, withthe outer edge portion of the sill 15 overhanging the sill 13 beyond theweather strip 34;, so that the sills will effectively shed rain andmoisture therefrom.

A stop bar 36 is hingedly mounted, as at 3T, at the inner edge of thesill 13 to swing upwardly and outwardly to a position along the lowerend of the frame 13, in order to prevent the f ame 13 from turning', andto also provide a neatl finish between the sills of the frames at theinner side of the window.

For convenience in swinging the bar 3G upwardly, when it is desired toturn the frame 13, a lifter 3S is. slidable verticallj1 in a guide 39carried by the sill 15 of the frame 13,` and has a finger 410 at itslower end disposed under the bar 3G, as seen in Fig. f1, and said lifterhas a linger piece or hook 41 at its upper end, whereby the lifter maybe conveniently raised so that the linger a() thereof swings the bar 36upwardly and inwardly. The bar 36 may then be swung downwardly out ofthe path of the sill 15 when the frame 13 is turned.

Outer and inner stop 'bars 4t2 are hingedly connected, as at 43, withthe lintel 19 of the frame 13 and are adapted to swing upwardly intorabbets 111 in the lintel 19 of the frame 12 to provide a snug and neatjoint between the two frames. The bars a2 are swungr upwardly yieldinglyby means of coiled springs connecting said bars and extending across thelintel 16 within grooves or channels 16 formed in said lintel, or thelintel may have bores or openings extending therethrough to accommodatesaid springs. i `In order that thebars 42 will bewung downwardlysmoothly when the frame 13 is turned from normal position and will swingupwardly snugly into engagement with the frame 12 when the frame 13 isreturned to normal position, the bars 42 are formed with rahbets 11Textending from those ends thereof which move under the lintel 19 whenAthe frame 13 is swung from normal position.

13 will cause the bars l2 to be swung down- `wardly so as to pass underthe lintel 19.

rlhe ends of the bars -12 opposite to the rabbets 47 are adapted to abutthe upper end portions of the stops 33 when the frame 13 is in anyposition, and the ends 50 of the bars l2 frein which the rabbets -17extend are cut obliquely so as to more into wedging engagement with theupper end portions of the stop bars 31 that are eut away and bevelled,as at 19, as seen in Fig. 6, for the engagement; of the bevelled ends 50of said bars 12. The clearance between the walls 43 of the rabbets Il?and edges of the lintel 19 are sullicient to permit the bars L1-2 toswing upwardly into place in overlapping relation with the lintel 19, orwithin the Iabbets L11 thereof, and as the bars 12 swing upwardly intoplace the ends 50 thereof come into tight contact with the bevelledportionsl 49 of the stop bars 31. "lhus, as seen in Fig. 1, the jointbetween the bars 31 and 42 is neat and plain. In fac-t, both the innerand outer sides of the window are plain and neat, without anyobjectionable protuberances or recesses such as would mar the appearanceof the window or would otherwise be objectionable.

lilith the present eonstructioinit is only necessary to swing the bar 36inwardly and downwardly, to permit theframe 13 to be turned, so that theouter side of the sash panels may be cleaned, or the window screenapplied to or removed from the outer side of the frame 13. The bars l2are automatially swung when the frame 13 is turned from and returned tonormal position, and the stop bars 31 and 33 are fixed to the respectiveframes.

The improvements may be embodied in a window construction made of metalas well as a construction composed `of wood, as shown. j

Having thus described the invention, what is claimed as new is:-

1. A `window comprising a 4main frame, a supplementary fra-me mountedfor turning movement therein about a vertical axis, and a springinfluenced bar hinged to the lintel of the supplementary frame to swingupwardly and overlap the lintel of the main frame, said bar having arabbet extending from one end to provide a clearance between the bar andthe lintel of the main frame.

2. A window comprising a main frame, a supplementary frame mounted forturning movement therein about a vertical axis, and a spring` influencedbar hinged to the lintel of the supplementary frame to swing `upwardlyvand overlap the lintel of the main frame, said bar having arabbetextending from one end to provide a clearance between the bar and thelintel of the main frame, said end of the bar being bevelled, and themain frame having a .stop bar for the contact of the Supplementary frameand proyvided with a bevelled portion for the conand adapted to swingupwardly into overlapping relation with the lintel of the main frame,and springs connecting said bars for swinging them upwardly.

5. A Window comprising a'main frame, a`

tary frame atrthe opposite edges thereof and" adapted to swing'upwardlyinto overlapping relation with the lintel of the main frame,

and springs connecting saidfbars for swinging them upwardly, each ofsaidbars having a rabbet extending from one end to provide a clearancebetween said bar and the lintel of the main frame.

G. A window comprising a main frame, a supplementary frame mounted forturning movement therein about alvertioal axis, stop bars hinged to thelintel of the supplementary frame at the opposite edges thereof andadapted to swing upwardly into overlapping relation with the lintel ofthemain frame, and springs connecting said bars for swinging themupwardly, eaoh of said bars having a rabbet extending from one end toprovide a Clearance between said bar and the lintel of the main frame,said ends of the bars being bevelled, and the main frame having stopbars for the Contact of the supplementary frame` and formed withbevelled porti-ons against which said ends of the rstnamed vbars areseatable when said first-V named bars-move into overlapping relationwith the lintel of the main frame. Y

7. A window comprising a main frame, a supplementary frametherein,`pivot means between the sills of said frames, and a pivottrunnion inserted upwardly through theVL lintel of the supplementaryframe and en# gaging the lintel of the main frame.

8. A window comprising a main frame, a supplementary frame l'thereinhaving a lintel with a lower parting ,strip groove, pivot means betweenthe sills of said frames, and a plate seated upwardly in said groove andhaving an upstanding trunnion extending through the lintel of thesupplementary frame and engaging the lintel of the main frame. p

9. A window comprising a main frame, a

Ysupplementary vframe mounted for turning i movement therein vabout avertical axis, a stop'bar hingedly connected with the sill of themainframe to swing to a position adja- 1 cent to thesill of thesupplementary frame to maintain the supplementary frame in normalposition, and means movably carried by the supplementary frame andhaving a portion to engage under said bar for swinging said bar upwardlyfrom said position. Y

l0. A window comprising a main frame, a supplementary frame mounted forturning movement therein about a vertical axis, a

Astop bar hingedly connected with the sill of the main frame to swing toa position adjacent to the sill of the supplementary frame to maintainthe supplementary frame in normal position, and a lifter carried by saidsupplementary frame and having a finger to be disposed bel-ow said barfor swinging said bar upwardly and away from the supple-l mentary framewhen said lifter is raised.
